1.How do we determine if a character state is ancestral or derived? 2.What is the topology of a phylogeny? How can the same tree be depicted in different ways? 3.How can phylogenies be used to map the evolution of character states and test evolutionary hypotheses?
a shared ancestral charactistic used in cladistics is found a. in only the two most recent ancestors b. only among the members of the ingroup c. in both the outgroup and in group d. in two of the outgroups e. only in the most distant ancestor
Taxa T1 T2 T3 0.5 A OOO 10.5 Question 9. In the phylogeny shown on the right, red represents the derived state for each of the three traits, and white represents the ancestral state. Changes in each trait are independent of changes in the other two traits. How many evolutionary changes are represented in the phylogeny? o oo (2 05 E oo a) four b) five c) six d) seven e) nine 0.5
7. Consider the evolution of land plants. a. According to the phylogeny of land plants, pores are an ancestral trait and stomata are derived. Explain why this is logical, in terms of the mutations that had to occur for these traits to evolve. (2 sentences max) (2 pts) b. Despite the advantages of stomata, Liverworts still thrive today and only have pores. Why? (2 sentences max) (2 pts)
VISUAL SKILLS Based on the phylogeny shown in Figure 34.25, identify the sister group for (a) reptiles; (b) squamates; and (c) the clade that includes crocodilians and birds. Concept Check 34.6 Contrast monotremes, marsupials, and eutherians in terms of how they bear young. Identify at least five derived traits of primates. MAKE CONNECTIONS Develop a hypothesis to explain why the diversity of mammals increased in the Cenozoic. Your explanation should consider mammalian adaptations as well as factors such as mass...

Answer all the questions please Name Check Your Understanding 9.2 Date Section 1 Cladistics or Evolutionary taxonomy? (Put a C or ET in the blanks.) Which school of systematics emphasizes: amount of change (evolution) of groups since the shared common ancestor. b recency of divergence from the common ancestor; branching patterns. 2 What are two characteristics that are primitive for mammals but derived for vertebrates? (Vertebrate groups are: fish, amphibians, reptiles, birds, and mammals.) (Hint: These would be features that...
Evolution ; Phylogeny ; Cladistics ; In a clade of turtles, shell color is either light or dark. The phylogeny of this clade is printed below, along with a number to label each species and drawings to show which species have light or dark shells. In your research, you have discovered a procedure that can reveal whether shell color is homologous between species 2 and another species. This procedure is time-consuming and expensive, however, because it requires detailed study of...
